Following the death of Pope Francis, the Vatican is preparing for its centuries-old tradition at the Sistine Chapel on May 7, the Conclave.
Over its 2,000 year history, spanning three millennia, the Catholic Church has had 266 popes.
When a pope dies, cardinals arrive at the Vatican to elect a replacement in a process called the conclave.
It will mark the beginning of the voting process by cardinals from around the world for a successor to Pope Francis, which could take days.
